Beginning with some great film footage of the early age of flight, including the explosion of the Hindenburg Zeppelin, this documentary then turns to modern day airship fanatic Dr. Graham Dorrington. It gradually emerges that Dorrington's friend Dieter Plage was killed flying a similar airship ten years earlier, and it is clear that Dorrington feels a certain degree of guilt over the death. Despite this, he persists in his quest to fly an airship over remote jungle in Guyana. The airship itself has a bit of a 'steampunk' look about it, and reminds me of Lee Scoresby's balloon in 'The Golden Compass'. With the help of this contraption, Dorrington aims to film the rainforest canopy - one the richest biospheres on earth.
The human element in this film is not so intense as with other Herzog documentaries, yet it does contain some amazing cinematography, such as the swifts flying madly into a waterfall, their secret kingdom. Perhaps the film would have been better if cut in length (it's not often you can say that about a Herzog film), or perhaps more footage of the rainforest canopy and less of the crew arguing. It's still worth watching, however.
